I gotta say this is one difficult manga to recommend people. Not due to its quality, which I felt was incredible, but the cover turns off the majority of people (for pretty good reason frankly). The cover though is all part of what makes this amazing. You see it expecting the most disgusting, depraved and horrifying hentai you can think of. The first few pages dig into that notion hard. Without context you don't want to continue cause you're 99% sure you know whats going to happen Then page 10 hits and it all becomes so much more clear. I'm amazed how much character and emotion andauthor could get out of such a short story. The majority of the manga has almost no environments and much of what we learn is through dialog alone. Normally that would be a death nail for a manga, but here it is played very well. There are select panels that just hit me hard, be it through a specific piece of dialog or how the character is drawn.

I don't want to spoil a thing because it is best to go in fairly blind.

Read it, then read it all over again. Those first 9 or so horrifying pages end up taking a whole new light once you are aware of the context.
